Inverse gamma distribution for landslide frequency-area estimations.

<p>(a) The gray diamond and blue circle indicate the landslide inventories of the Guatemala and Taiwan case. The red line is the reference distribution with ρ = 1.4, <i>a</i> = 1.28×10⁻³ km², <i>s</i> = 1.32×10⁻⁴ km². The solid and dashed yellow lines represent the distribution with 0.8ρ and 1.2ρ, respectively. Their corresponding <i>r</i>² to the reference reach 0.973 and 0.976, respectively. (b) Change of total area and large landslide proportion is associated with the change of the exponent.
